sorry for asking what is probably an obvious question to many on here but...i have my ps3 connected to my denon amp via optical cable, should the output be set to bitstreat or linear? i think its currently bitstream.
Bugger, I have just seen what receiver you have in your sig, and I was looking to buy that one too, as I assumed due to its specs, it would give uncompressed to 7.1. I guess the HDMI function on it is just for switching purposes rather than full throughput then...
Bitstream will produce the best sound, but very few if any amps currently support the hd audio files via bitstream. Therefore if your amp supports 5.1 lpcm then use that method.
Basically if you use lpcm the ps3 is dividing the bitstream (the original source as it is stored on the disc) into 5 channels and then decoding the dd (or dts) track and encoding it as 5 lpcm.
I don't believe (although i could be wrong) that optical has the bandwidth to carry a 5 channel lpcm score. Either way the studios don't allow it to be sent over optical and therefore the only way to get a amp to reconise it is via hdmi.
i've been testing the sound through my sony 7100es and ps3 via hdmi for uncompressed 5.1 pcm sound and switching between optical bitstream. imho i found the sound via optical more punchier and dynamic . does anyone think the same?
p.s. bitstream as the name suggest is a bit perfect pass of the original soundtrack as stored on the media. Any other method of passing data requires the audio to be initially decoded from the mpeg original and then recoded into something else, i.e. lpcm.
If you amp can't decode the bitstream then it needs decoding anyway.
